Chickenpox (varicella) is a contagious illness that causes an itchy rash and red spots or blisters (pox) all over the body. It takes about 1 or 2 days for a chickenpox red spot (macule) to go through all of its stages. This includes blistering, bursting, drying, and crusting over.
Is chicken pox a papule?

What are the 3 types of lesions?
They tend to be divided into three types of groups: Skin lesions formed by fluid within the skin layers, such as vesicles or pustules. Skin lesions that are solid, palpable masses, such as nodules or tumors. Flat, non-palpable skin lesions like patches and macules.
How do you describe chicken pox lesions?
Once the chickenpox rash appears, it goes through three phases: Raised pink or red bumps (papules), which break out over several days. Small fluid-filled blisters (vesicles), which form in about one day and then break and leak. Crusts and scabs, which cover the broken blisters and take several more days to heal.
What is a Macule skin lesion?
